One of the most intriguing properties of cellular membranes is their ability to fuse with one another. Within a living cell numerous membrane fusion and fission events occur, mediating the flow of cellular constituents between different cell organelles. How do two adhering membranes achieve this complex merging operation within the restriction posed by

Regulation of intracellular membrane transport
Current Opinion in Cell Biology, 1992A number of proteins that are necessary for membrane transport have been identified using cell-free assays and yeast genetics. Although our knowledge of transport mechanisms remains limited, common themes are clearly emerging. In particular, specific GTP-binding proteins appear to be involved, not only at all steps of membrane traffic but also at more ...

Intracellular membrane morphology
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1995The membrane-bound organelles on the exocytic and endocytic pathways are linked by vesicles which bud from one membrane compartment, carrying selected cargo, and fuse with the next on the pathway. The principles underlying this vesicle-mediated traffic go a long way towards explaining the morphology of these intracellular organelles and their behaviour

Membrane tethering in intracellular transport
Current Opinion in Cell Biology, 1999Studies of various membrane trafficking steps over the past year indicate that membranes are tethered together prior to the interaction of v-SNAREs and t-SNAREs across the membrane junction. The tethering proteins identified to date are quite large, being either fibrous proteins or multimeric protein complexes.

Journal of Cell Science, 1953
ABSTRACT Spheres that stain with neutral red in cephalopod neurons show changes with variations in the tonicity of the surrounding medium. In hypertonic solutions the surface becomes shrunken and the stainable matter restricted to crescents or granules at the side of the sphere. These processes are reversible.

Fusion of biological membranes plays an important role in cell structure and function. It is essential for organelle biogenesis, vesicle targeting, constitutive and regulated exocytosis, endocytosis, pathogen invasion of host cells, sperm-egg fusion and skeletal muscle formation.

Enzymology of intracellular membrane fusion
Klinische Wochenschrift, 1991A combination of cell-free biochemical and morphological studies has revealed that a coated bud-coated vesicle transport system shuttles newly synthesized proteins through the successive processing compartments of the Golgi apparatus. These "Golgi coated vesicles" operate in a manner formally analogous to the clathrin coated pit-coated vesicle system ...

Genetic Defects of Intracellular-Membrane Transport
New England Journal of Medicine, 2000The compartmentalization of functions into distinct membrane-bound organelles is a central characteristic of cells. The protein and lipid composition of these organelles is unique, a factor that is vital for their proper function. This necessitates tightly controlled transport of biomolecules from their sites of synthesis or uptake to specific ...

Intracellular Parcel Service: Current Issues in Intracellular Membrane Trafficking
2014Eukaryotic cells contain a multitude of membrane structures that are connected through a highly dynamic and complex exchange of their constituents. The vibrant instability of these structures challenges the classical view of defined, static compartments that are connected by different types of vesicles. Despite this astonishing complexity, proteins and

CD95 ligation and intracellular membrane flow
Biochemical Journal, 2008Whereas ligation of the CD95 death receptor in the plasma membrane of so-called type I cells leads to a direct caspase 8-dependent activation of downstream effector caspases, mitochondrial amplification of caspase 8-derived signals is required in so-called type II cells in order to execute apoptotic cell death.
